Frank Atashili

"I've had the pleasure of working with Precious as part of the Integration Monitoring team at checkout.com, where he worked as our front-end engineering expert. From the start, Precious has consistently impressed me with his technical expertise, creativity, and dedication. He built the first version of our UI entirely from scratch, a task that required not only strong coding skills but also a deep understanding of user experience and design principles. Precious is a proactive problem-solver, always eager to take on challenges and push boundaries to deliver high-quality results. His ability to balance both the technical and aesthetic aspects of front-end development has been key to the success of our project. Beyond his technical skills, Precious is a great team player—collaborative, communicative, and always willing to share his knowledge with others. I highly recommend Precious for any future roles, as I am confident he will continue to excel and bring value to any team lucky enough to have him."
